ripple can understand as rise in sine wave.thus ripple-less means a straight line parallel to x-axis i.e. bump-less line.
capacitor is a component which store charge.it charge through a.c. and behave as battery on full charge.and we all know battery gives a d.c. i.e. ripple less graph.

What is the ripple factor of full wave rectifier?
although the AC signal is rectified the output which we get is the pulsating DC which is not desired because many appliances wok on plain DC voltage . The pulsating DC can be viewed as AC + DC component of the signal ripple factor of a rectified circuit is the ratio of AC component of signal to the DC component of the same rectified output signal. higher the ripple factor says that the signal is not smooth so lesser is its application. the components used to smooth these type of signals or to remove the 'ripple voltage' as called filters
What happens to the output voltage of a rectifier if the capacitor becomes very leaky?
A leaky capacitor will act like a load therefore decreasing the DC and increasing ripple eventually the capacitor it will self destruct because of heating probaly taking out the rectifiers as well.
How can a capacitor reduce the effects of ripple voltage?
The smoothing capacitor converts the full-wave rippled output of the rectifier (which is left over AC signal) into a smooth DC output voltage A smoothing capacitor after either a half-wave or full-wave rectifier will be charged up to the peak of the rectified a.c. Between peaks of the a.c. the stored voltage will drop by a degree dependent on how much current is drawn from it by the load. The larger the value of the capacitor, the less drop there will be, and therefore less ripple when loaded.
How do you calculate the capacitance value of filter capacitor for full-wave bridge 12VDC power supply?
THe Filter capacitor value depnds on the maximum current I of the Power supply , Switching frequency and the permissible ripple C= (I * (1/2f ))/ ( V * %Ripple) - for a full wave rectifier C= (I * (1/f ))/ ( V * %Ripple) - for a Half wave rectifier Where C= Capcitance in Farads I = Current in Amps f = Switching Frequency V = Nominal voltage in this case 12 V Reji J Thoppil
How many uf capacitor for using 6V 100amp rectifier?
To determine the required capacitance for a 6 volt 100 amp rectifier, you would need to know the ripple voltage that the circuit would tolerate. You would also need to know the ripple frequency. More specifically, you would need to know the time from one peak value to the intersection of the capacitor's voltage decay curve and the next turn on point for the rectifier.Let's say that the tolerated ripple voltage is 1 volt, and that the ripple frequency is 120 hertz, as provided by a full wave rectifier. This is a period of 8.3 millseconds. The actual time from ripple peak to ripple trough is actually slightly less than 8.3 millseconds, but that is a function of ripple slope, as somewhat complex calculation, so lets use 8.3 millseconds, which will be conservative.1 volt in 8.3 millseconds is 120 volts per second. Plug that in to the equation for a capacitor ...dv/dt = i/c..., along with the current of 100 ampere, solve for c and you get ...dv/dt = i/c120 = 100/cc = 100/120c = 0.83 faradsNow, 8.3 farads is a very large capacitor. Lets improve the situation with a three phase rectifier. In that case, the ripple frequency is 360 hertz, or 2.8 milliseconds, requiring a 0.28 farad capacitor, still a large value, but better than 0.83 farads.
How can capacitor smooth or reduce the ripple of the voltage produced by the rectifier?
when rectifier is on, the capacitor is almost transparent (it charges to the voltage provided from the rectifier) when rectifier is off, capacitor holds the peak voltage since it stored a charge during rectifier on time.
What is ripple factor of the Full-wave rectifier?
The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482
What is the importance of ripple factor?
Ripple factor ripple factor is very important in deciding the efficiency of the rectifier .ripple factor give the total power converted AC input to the DC output. Ideal ripple factor should be zero and power factor 1. Ripple factor of half wave rectifier 1.21 and full wave rectifier is 0.48.

What is the value of the ripple factor of a half wave rectifier?

How you determine ripple factor of a half wave rectifier?
when a.c convert in d.c then some components of a.c remain with it called ripple factor
What will happen if the capacitor is removed from the DC charger?
It will increase the ripple factor that the capacitor is in the circuit to smooth out.
How do you determine the size of acapacitor in a rectifier circuit?
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.
Significance of the ripple voltage on a rectifier circuit?
A: It really depends on the load requirement . Example driving a relay hi ripple with no capacitor is an advantage in efficiency for a sensitive amplifier it will cause mayhem with the performance
What will be the effect on ripple factor if the value of capacitor is reduced?
Ripples will increase if capacitance is decreased.
Which rectifier have highest ripple frequency?
The three phase bridge rectifier has the highest ripple frequency. In a 60 Hz system, the ripple frequency would be 360 Hz. If it were a one phase bridge rectifier, the ripple frequency would be 120 Hz.
